The 718 Boxster PDK offers optional Porsche Active Safe, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The TT doesn't offer collision warning or crash mitigation brakes.

Both the 718 Boxster and the TT have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available blind spot warning systems.

Reliability

To reliably power the ignition and other systems and to recharge the battery, the 718 Boxster has a standard 175-amp alternator. The TT’s 140-amp alternator isn’t as powerful.

To reliably start during all conditions and help handle large electrical loads, the 718 Boxster has a standard 450-amp battery. The TT’s 330-amp battery isn’t as powerful.

J.D. Power and Associates rated the 718 Boxster third among compact premium sporty cars in their 2023 Initial Quality Study. The TT isn’t in the top three.

J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that Porsche vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Porsche above average in initial quality. With 54 more problems per 100 vehicles, Audi is rated below average.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Porsche vehicles are more reliable than Audi vehicles. J.D. Power ranks Porsche above average in long-term dependability. With 30 more problems per 100 vehicles in the first three years of ownership, Audi is rated below average.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Porsche vehicles are more reliable than Audi vehicles. Consumer Reports ranks Porsche 11 places higher in reliability than Audi.

Speed in 1/4 Mile	112 MPH	n/a	99 MPH	108 MPH
Top Speed	170 MPH	n/a	128 MPH	155 MPH

The flat cylinder configuration of the boxer engine in the 718 Boxster lowers its center of gravity, enhancing handling stability. The TT doesn’t offer a boxer engine configuration.

Fuel Economy and Range

An engine control system that can shut down some of the engine’s cylinders helps improve the 718 Boxster GTS 4.0/Spyder’s fuel efficiency. The TT doesn’t offer a system that can shut down part of the engine.

Regenerative brakes improve the 718 Boxster’s fuel efficiency by converting inertia back into energy instead of wasting it. The TT doesn’t offer a regenerative braking system.

Regardless of its engine, the 718 Boxster’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The TT RS doesn’t offer an automatic engine start/stop system.

The 718 Boxster’s optional fuel tank has 2.4 gallons more fuel capacity than the TT (16.9 vs. 14.5 gallons).

Brakes and Stopping

For better stopping power the 718 Boxster’s brake rotors are larger than those on the TT:

	718 Boxster	718 Spyder RS CCB	TT 45 TSFI	TTS Coupe
Front Rotors	13 inches	16.1 inches	12.3 inches	13.3 inches
Rear Rotors	11.8 inches	15.4 inches	11.8 inches	12.2 inches

The 718 Boxster’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the TT 45 TSFI are solid, not vented.

The 718 Boxster stops much shorter than the TT:

	718 Boxster	TT
70 to 0 MPH	143 feet	157 feet	Car and Driver
60 to 0 MPH	108 feet	113 feet	Consumer Reports
60 to 0 MPH (Wet)	119 feet	122 feet	Consumer Reports

Tires and Wheels

For better traction and acceleration, the 718 Boxster has larger standard rear tires than the TT (265/45R18 vs. 245/40R18). The 718 Spyder RS’ rear tires are larger than the largest rear tires available on the TT (295/30R20 vs. 255/30R20).

Suspension and Handling

The 718 Boxster S handles at 1.10 G’s, while the TT 45 TSFI Roadster pulls only .99 G’s of cornering force in a Motor Trend skidpad test.

The 718 Boxster S executes Motor Trend’s “Figure Eight” maneuver 1.6 seconds quicker than the TT 45 TSFI Roadster (23.1 seconds @ .89 average G’s vs. 24.7 seconds @ .77 average G’s).

Cargo Capacity

The 718 Boxster has a much larger trunk with its top down than the TT Roadster (9.6 vs. 7.5 cubic feet).

To make loading groceries and cargo easier when your hands are full, the 718 Boxster’s available trunk can be opened just by holding your hand near the emblem on the trunk, leaving your hands completely free. The TT doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Porsche service is better than Audi. J.D. Power ranks Porsche third in service department satisfaction. With a 14% lower rating, Audi is ranked 8th.

Ergonomics

When three different drivers share the 718 Boxster, the optional memory system makes it convenient for all three. Each setting activates different, customized memories for the driver’s seat position, steering wheel position, outside mirror angle and climate settings. The TT doesn’t offer a memory system.

The 718 Boxster’s optional easy entry system raises the steering wheel and glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The TT doesn’t offer an easy entry system.

The 718 Boxster’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The TT does not have an oil pressure gauge.

In case of a sudden change of weather, the 718 Boxster has a standard remote convertible top that can be raised from a distance to protect the interior of the vehicle from damage. On a hot day the 718 Boxster has a standard remote opening feature, to lower the top from outside. The TT doesn’t offer a remote top, so the driver will have to run to the car, get in, turn the ignition on and raise the top to prevent the interior from being damaged.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The 718 Boxster has standard headlight washers to keep headlight output high. The TT doesn’t offer headlight washers.

While driving with high beams on, sensitive light sensors available for the 718 Boxster detect other vehicles which could be blinded and automatically switch to low beams. The TT doesn’t offer automatic dimming high beams.

The TT’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The 718 Boxster’s standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

Optional air-conditioned seats in the 718 Boxster keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The TT doesn’t offer air-conditioned seats.

On extremely cold winter days, the 718 Boxster’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The TT doesn’t offer a heated steering wheel.

The 718 Boxster’s standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The TT doesn’t offer dual zone air conditioning.

To keep a safe, consistent following distance, the 718 Boxster (except Manual) offers an optional Adaptive Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The TT doesn’t offer an adaptive cruise control.
